Figure 9-4. Drive Interface Connectors

When attaching the interface cable to a drive, be sure to
match the colored strip on the cable to pin 1 of the drive's
interface connector. For the location of pin 1 on the
drive's interface connector, see the documentation that
came with the drive.
CAUTION: If the pin-1 end of the connector does
not match the colored strip, the drive may not
operate or the system and/or drive may be
damaged.
When disconnecting an interface cable from the system
board, be sure to press in the locking tabs on the cable
connector before disconnecting the cable. When attach-
ing an interface cable to the system, be sure that the
locking tabs snap into place, ensuring that the cable is
firmly attached to the connector on the system board.
E
IDE Drive Addressing
All EIDE devices should be configured for the Cable
Select jumper position, which assigns master and slave
status to devices by their positions on the interface cable.
When two EIDE devices are connected to a single EIDE
interface cable and are configured for the Cable Select
jumper position, the device attached to the last connector
on the interface cable is the master or boot device
(drive 0) and the device attached to the middle connector
on the interface cable is the slave device (drive 1). Refer
to the drive documentation in your upgrade kit for infor-
mation on setting devices to the Cable Select jumper
position.
With the two EIDE interface connectors on the system
board, your system can support up to four EIDE devices.
EIDE hard-disk drives should be connected to the EIDE
interface connector labeled "IDE1." (EIDE tape drives
interface
and CD-ROM drives should be connected to the EIDE
cable
interface connector labeled "IDE2.")

nstalling Drives in the Drive Cage
The user-accessible drive cage at the front of the chassis
can hold up to two half-height, 5.25-inch devices—typi-
cally tape drives or CD-ROM drives—and one 3.5-inch
diskette drive on the 3.5-inch bracket attached to the top
of the cage.
NOTE: This section covers the physical installation of
devices in the drive cage; it also covers cabling and
system configuration information for diskette drives, non-
SCSI tape drives, and non-SCSI CD-ROM drives. (See
"Installing SCSI Devices" found later in this chapter for
information on installing SCSI devices.)
Installing a Drive That Uses a Built-In
Drive Interface in a 5.25-Inch Drive Bay
This subsection describe how to install the following
items:
•
A diskette drive or tape drive that uses the diskette/
tape drive controller or the secondary EIDE interface
•
A CD-ROM drive that uses the secondary EIDE
interface
NOTE: For instructions on installing a diskette drive in
the 3.5-inch bay, see the next subsection,"Installing a
Diskette Drive on the 3.5-Inch Bracket."
1. Unpack the drive and prepare it for installation.
Ground yourself by touching an unpainted metal sur-
face on the back of the computer, unpack the drive,
